Evaluation of Soft Multifocal Lenses in Presbyopic Previous Contact Lens Wearers

The purpose of this study is to evaluate the wear experience of people with presbyopia who previously dropped out of contact lens wear when fit with a Delefilcon A soft lens multifocal lens. Investigators expect to enroll a relatively equal amount of former soft multifocal contact lens wearers who dropped out due to poor vision at distance or near and single vision wearers who dropped out due to poor near vision. The key endpoints include Visual Analog Scale survey of lens wear symptoms (comfort, dryness, vision) with contact lenses and assessment of the participant's quality of life with the Dailies TOTAL1 Multifocal® contact lenses.
